Li Xiuning knew her father's temperament and saw something good. After seeing it, she wanted to take it for herself. She was really afraid that she would come to snatch her steel mill. If she repeatedly caused conflicts with Li Yu, her father would suffer in the end. So she ran to the palace to explain the situation.

After hearing Li Xiuning's introduction to the steel plant, Li Yuan was shocked when he knew that the output of the steel plant exceeded that of the Tang Dynasty for decades a year. He really wanted to snatch it, but he had issued an imperial edict to agree to his daughter to build the iron plant. Could it be that he would be untrustworthy?

Moreover, that guy Li Yu is not a fuel-efficient lamp. Don’t let the steel factory rob it and he can’t get it out of Taiwan.

When Li Xiuning left the palace, Li Yuan immediately sent someone to find his old friend Pei Ji to discuss the matter, and finally came up with a solution that was not a solution.

The next day, Li Xueyi quickly found dozens of kiln workers and hundreds of prisoners of war. On a hillside near Yaozhou Coal Mine, dozens of kiln workers and hundreds of prisoners of war quickly dug more than a dozen empty kilns and reinforced them with refractory materials.

As long as coking technology is available, coking is actually very simple. Coking refers to the heating of coking coal to about 1,000 degrees under air isolation conditions until it becomes coking. Coke is produced by thermal decomposition and coking, coke oven gas and other coking chemistry, and the process of the product. Metallurgical coke has a high carbon content, which is an important fuel and reducing agent for blast furnace ironmaking, and it is also a proppant and loosening agent for the entire blast furnace column. The most important point is to prevent air from entering the kiln.

The new kiln was first heated and removed from wet. Then, under the command of the engineers of the Dragon and Phoenix Empire, the coal was filled into the kiln pit and sealed with clay.

After a night of refining and a morning of cooling, the next afternoon, Li Yu, Li Xiuning and others who had not returned came to the kiln early to see the situation of the coke.

At the order of Li Xueyi, several assistants standing at the kiln entrance smashed the sealed kiln entrance with a sledgehammer. Then, the assistants entered the kiln and lifted the coke out of the kiln in a bamboo basket.

The coke quenched is discharged on the tilted cool coke table for cooling. The coke usually stays on the cool coke table for about 30 minutes to evaporate the moisture and quench a few unextinguished red cokes.

"I didn't expect that after turning coal into coke, the coke became half lighter." Li Xiuning didn't bother with anything, picked up a piece of coke on the stage, weighed it, and looked surprised.

"Refining all the impurities in the coal, so the coke becomes lighter." Li Yu looked at Li Xiuning's pretty face and said, "You will not understand this principle."

"Of course I understand!" Li Xiuning stared at the apricot and said, "I was surprised, I was happy, can't I say it?"

When Li Xueyi saw that the two wanted to argue again, she shook her head and did not persuade her. She knew that they liked to bicker, which was their fun.

"Miss, son-in-law, Duke Ying is here!" Li Xueyi pointed to the warrior walking by in the distance.

"Hahaha……"

A burst of generous laughter came, who wasn't the warrior?

Li Yu turned his head and looked at the warrior walking in the distance, and probably understood his purpose in his heart.

"Duke Ying, why do you have time to come today?" But he smiled in his heart, and his face still had a constant smile.

Li Yu said a pun. First, it was a greeting tone, and second, it was a question of whether you were paying attention to the court when you came to the steel factory.

"Haha... I heard you want to refine coke, but I ran straight to it after hearing this. Alas! The imperial court has been refining coke for more than a year, and they are still arguing with each other. I don't want to see whether they can refine coke." The warrior laughed heartily, not caring about what Li Yu said.

"This is the refined coke. Look, the process is actually very simple, not too complicated." Li Yu said with a sneer on his face: "I didn't expect that the court has not yet tried it out for more than a year. The efficiency is really high!"

The warrior did not respond, but just shook his head helplessly. He himself was also dissatisfied with the efficiency of the court's affairs.

"Is this coke?" Samurai Ji picked up a piece of coke and said, "I don't know how the combustion effect is?"

Li Yu was too lazy to explain anything, so he asked the helper to bring a brazier and picked up a few pieces of coke and threw it into the brazier. After a while, the coke started to burn in the brazier.

The warrior took the coke on the cold scorch platform and looked at the brazier again: "The coke you made is light, big, smokeless, and flammable, and I feel it is not bad at all compared to the top charcoal. And the temperature is higher than the charcoal, which is really a good thing. A kiln turned the coal with smoke into the best coke, but the court's delayed work efficiency and such good coking technology have not been successful yet."

After saying that, Samurai Ji shook his head helplessly, with a helpless look on his face.

"Duke Ying, aren't you planning to buy coke today?" Li Yu was too lazy to go around in circles, and it was meaningless, so he simply asked for the purpose of the visit.

"It's not about buying coke, but about other things I want to discuss with you." Samurai said: "I heard that you are going to set up an iron factory. It is said that the output of this steel factory is more than 30 times that of the current Tang Dynasty. The investment will not be small. Do you need to invest in shares?"

"Stake in shares? It's a stumping saying that Duke Ying wants to participate?" Li Yu said: "But will your emperor allow the steel produced by the steel mill to be sold privately to private individuals?"

"No, no, no, it's not that I invested in the shares, it's because the court wanted to invest in the shares." Samurai said: "In this way, the steel mill will be a joint stock, and it can be sold at will in the future. There are no other restrictions, and it will be mutually beneficial and win-win."

"Oh? How can we win-win for mutual benefit?" Li Yu was not angry, and still had a smile on his face.

"That's right. If you hand over all the produced steel to the court, and when the court sells it all, how about the court only withdraws 60% of the cost?" Warrior talked freely, as if he knew everything about the steel factory.

"Haha, I heard it right?"

Li Yu sneered, clearly laughing in anger: "You charge 60% of the profit? We paid the workers and the messy capital is withdrawn. We have been working for the imperial court for nothing?"

"How could you lose?" said Wu Shiji. "Your steel mill has the support of the court. In the future, the price of steel can be sold at a high price. Think about it, if the steel is produced and cannot be sold, your losses will be great. Also, steel is the exclusive operation of the court. If the court takes back the operating rights, you will lose both people and money and may be in jail. Why bother?"

"So, the court is planning to prevent this steel plant from being built?" Li Yu's tone became unkind.

Suddenly, Li Yu's murderous aura was boiling, his eyes were like a sharp blade, and he looked coldly at the direction of Chang'an: "Very good, I think your emperor is interested in this steel factory. He plans to annex this steel factory in the name of investing in the company! It seems that some people think that the world has returned to their hearts, and power has already made his ambitions expand. What have they forgotten?"

Looking back at Li Xiuning's difficult appearance, Li Yu sighed, and his anger disappeared in an instant, and he seemed a little helpless.
